Inspiron M531R-5535 CD/DVD upgrade/ replacement?

The CD/DVD drive on my laptop *** out on me a couple days ago.  Tray opened fine but when I closed it with the CD inside it started making a lot of noise and the tray wouldn't open again without using the manual release.  Won't read anything I put in there now either.  After doing a diagnostics test and checking software and drivers I believe it's a mechanical failure in the actual drive.  So, since it needs replacing, could someone tell me if it's possible to upgrade this model of laptop to a drive that plays Blurays?  I shopped around but my laptop doesn't seem to match the system requirements listed on the drive boxes I found in stores.  Everything seems to require an Intel Pentium IV processor with 2.40 GHz and my PC is running an AMD A8-5545M APU at 1.70GHz so I'm assuming they're not compatible.  I've been searching around on Google and can't find a site that lists Bluray drives with tech specs so I can figure out if anything will run with the laptop I have.

If I can't do this upgrade, where/ how can I find a replacement CD/DVD drive?  I've got a DU-8A5HH111C DVD/ CD rewriteable drive in there now.  Do I have to replace it with the exact same model or are these kinds of drives somewhat interchangeable?  I found this specific one for sale online but I'd have to wait for it to ship from Japan so I was hoping to find somewhere in The States that sells it so I can get it quicker.  Thanks!
